Passive Cooling of Housing by Natural Ventilation
Kharchi R., Imessad K.
Abstract:
The building's form and thermal characteristics largely govern the amount of energy consumed by a building. To avoid major flaws of the design, an architect needs to include the evaluation of the building's energy consumption in the earlier stages of the design process. If energy efficiency is not adequately considered during these stages, higher operating cost will accrue over the life of the building. In recent years, scientists, engineers and architects designed successful innovative buildings that use passive cooling techniques, such as natural ventilation. The house studied is a pilot project undertaken jointly by the Centre for Development of Renewable Energies (CDER) and the National Centre for Studies and Research of integrated building (CNERIB) under the MED-ENEC project (Mediterranean Energy Efficiency in Construction structure). The house subject of study is 65 m? surface area, located in the Algiers region characterized by a Mediterranean climate with relatively mild winters and hot, humid summer. This work is to study the comfort inside the house in the summer without air conditioning, ventilation only is considered. Numerical simulation is made under TRNSYS, the results compared with measured values are conclusive.
